MANGLE.

SPECIFICATION forming part of Letters Patent No. 554,584, dated February 1 1, 1896.

Application filed April 15, 1895.

T0 aZZ whom it may concern:

Be it known that W6,ALEXANDER M. DOLPH and JOHN II. SLACK, residing in Cincinnati, county of Hamilton, State of Ohio, and I/VIL- LIAM A. SAUNDERS, residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Mangles, of which the follow ing is a specification.

The object of our invention is to provide a stationary drying drum operating in conjunction with smoothing-rolls and concave beds, around which drum the garments to be smoothed and dried are carried by means of an endless apron after having been operated on by the mangle-rolls.

Another object of our invention is to provide means for removing the endless apron from contact with the drying-drum.

Another object of our invention is to provide means for removing the mangle-rolls from close contact with the concave beds when the machine is not in operation.

Another object of our invention is to provide spring-pressure applied to the journalboxes of the mangle-rolls so as to yieldingly adjust them to the concaves and to hold them in the adjusted position.

Another object of our invention is to provide an improved mangle-roll which is so constructed as to prevent the staining of the garments by rust from the metal parts of said roll, and also to provide means for taking up the contraction and expansion of the periphery of said roll.

The features of our invention will be more fully set forth in the description of the accompanying drawings, making a part of this specification, in which Figure 1 is a sectional elevation on line :1: 00, Fig. 4. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a central vertical section of one of the mangle-rolls. Fig. 4 is a front elevation with the steps and clothes-basket removed and parts of the driving mechanism omitted on the left-hand side. Fig. 5 is an inside sectional elevation of one end of the frame on line y y, Fig. 4. Fig. 6 is'a vertical sectional elevation of the spring-housing operating the roller-journals. Fig. 7 is a transverse section of Fig. 6.

Fig. 8 is a detailed view of one of Serial No. 545,825. (No model.)

by means of rods cl d upon the stud-shafts D D. The rolls 0 c are driven by the following mechanism:

' E represents the main driving-shaft. Upon it at each end is mounted a pinion 6, each of which meshes with and drives a pinion F upon the stud-shaftf, there being two pinions F and two stud-shafts f. G represents a sprocket chain engaging with sprocket- Wheel 9, secured to pinion F on stud-shaft f and with sprocket-Wheel g on the shaft h, around which the chain G travels. On shaft h are mounted two other sprocket-wheels which drive the sprocket-chains H H, transmitting motion to sprocket-wheels H H These in turn drive the sprocket-wheels H II on the ends of the shafts of the rollers c c. The endless apron C is thus caused to continuously travel around the periphery of the drying-drum. In order that the said apron may be removed from contact there with when the machine is not in operation, we provide the following instrumentalities:

I represents a shaft journaled to arms of the yoke-guards J, each of which guards is simply a horizontally-arched frame of such form as will permit passage of the mechanism concerned in moving the apron to and from the drum. To said shaft I is keyed or secured a crank-arm j, which engages with the link 21, which is pivoted to the stirrup is engaging the rod cl. K represents a stirrup connecting said rod at through link K with the crank-arm L.

L represents a connecting-rodconnected to the crank-arm L, and to the stirrup L secured to the rod d. When the shaft I is turned in its bearings the link i' is moved from the position shown in Fig. 8 to the posi-' tion shown in Fig. 5. This moves inwardly the pivotal rods (Z (1, upon which the rollers c c are journaled, thereby drawing the apron G carried on said rolls up against the periphery of the drum. A reverse movement can ries the rollersc c outwardly and loosens the apron, as shown in Fig. 2, thereby preventing it from becoming unduly heated when the same is not in use.

i represents a stud on the crank-arm j, which travels over to a bearing-contact with the guard-arm J, as shown in Fig. 5, to arrest the motion and hold the rolls 0 c in a rigid position for operation, the link i and crankarm being then substantially in line with each other.

M N represent the mangle-rolls, which are revolved and operated in conjunction with the concave beds or 72., which concave beds are heated in the usual manner, the devices for which are not shown. The mangle-rolls are constructed as follows:

0 represents a series of arms of spider form extending the whole length of the roll. 0 represents a series of connecting-ribs cast at intervals along the arms. 0 represents a series of wooden segments securely attached to said ribs 0 and form the barrel of the cylinder. P represents the outside facing for said roll and is preferablyformed of zinc, a sheet of which is wrapped around said roll, the ends not quite coming in contact, leaving the space 1) between them. 12 represents a piece of zinc seated in the recess formed between the ends of the facing. 0 represents a strip of metal tacked to one end of the facing-sheet and projecting out and overhanging the other end. The object of this is to allow the contraction andexpansion of the sheet metal without interfering with the cover of the roll and to confine the facing on the roll. Said metal facing is covered over with suitable fibrous material. By this construction the discoloring of the garments by contact with the roll is prevented, and the contraction and expansion are duly provided for inside of the outer covering. These rolls M N are journaled at each end in sliding boxes Q Q. The concave beds m n are rigidly connected to the frame in any suitable manner.

\Vhen the mangle-rolls are not in use it is desirable to remove them from close contact with the concave beds, so that the covering will not become unduly heated or scorched. To accomplish this we provide the following instrumentalities S represents lever-arms pivoted to the sides of the frame at one end, the opposite end being hinged respectively to the lever-arms S, as shown in Figs. 6 and 7. T represents an arm provided with a housing in which is seated the coil-spring T, one end of which seats against the arm S. The arms T S S and their connected parts are applied to each side of the machine. To said arms S are attached crank-arms R R connecting with the sliding boxes Q Q' in which the man gle-rolls are journaled. Each arm T is provided in one end with a slot .5" that connects with the hinge-pin or pivotal connection of the arms S S to permit a yielding connection of the several arms. Said arms R R are pivoted by ears .5 to the sides of the frame. t 25 represent loose hinged connections of the armsR R with the journal-boXes Q 0. The arm T is supported upon a sliding support U. V represents a screwthreaded shaft journaled in bracket V and screwed into threads in the sliding support U. WV represents a beveled pinion on the end of each shaft V. The pinions TV are driven by the beveled pinions \V, to which motion is imparted by means of the hand-wheel X on shaft X, to which said beveled pinions 'W are keyed. \Vhen said shaft X is revolved the pinions YV drive the pinions \V and move the sliding supports U out or in, as the case may be, which transmits motion through the arms S R R to the journal-boxes Q Q and simultaneously adjusts said man gle-rolls to or from their respective concave beds. In order that the tension of each spring T may be regulated we provide an adjustable seat Y operated by a nut on the screw Y, by means of which the tension is increased or decreased as desired.

At the upper front portion of the machine, adjacent to the concave bed a, is a basket Z to receive the garments, and steps Z may be provided to give access to the basket.

The garments are fed forward from the basket Z between the concave bed or and the roll N, from which they are delivered to the roll M and passed between it and the concave bed m, from whence they are delivered onto the drum B, being fed forward on the drum by roll 1'.- This roll is driven from the roll M by means of the chain belts 5, one at each side of the machine, the roll 4being connected to the shaft of the roll M by sleeves 6 7 and connecting-rods 8, the roll resting by its own weight on the face of the drum 1}. 9 represents an arm pivoted to the hinged arm S at each side of the machine, which lift roll t from the face of the drum at the same time that the mangle-rolls M N are shifted away from the concave beds. As the garments pass from roll 4 they are caught by the apron and carried around the drum B upon which they are pressed and dried and delivered onto the table 10.

It will be understood that the devices for adjusting the mangle-rolls and for driving and tightening the endless apron and for movin g it to and from the stationary drying-drum, and the devices for operating the roll t, are duplicated on opposite sides of the machine.

\Vhen. the machine is not in operation the mangle-rolls are moved out of contact with the heated parts and the endless apron is slackened as described.

In order to strain the apron we provide the following devices: The table 10 is made ex- 11 represents legs supported on casters. The top of the table travels on ways formed on rails 12. 13 represents rack-bars secured to the table,-and roller 1 is j ournaled thereon. 1% represents a shaft journaled on the pillow-blocks 15 attached to the rails 12. 16 represents a pinion engaging with a rack 13, a pinion and rack being located at each side of the machine. 17 represents a handwheel on shaft 14. The hand-wheel is turned to run the pinions 16, moving the rack-bars to move the table out or in. The roller 1 moves with the table and controls the strain of the apron.

In order to cause the apron to travel in a true path on the face of the drum we provide the following devices to regulate the lateral strain of said apron: Roll 3 is journaled at one end on a swiveling journal-box 18, and the journal upon the opposite end is supported upon crank-arm 19. 20 represents a crank connecting-rod hinged at one end to the crankarm 19 and at the other end to setting-lever 21. 22 represents a toothed segment; 23, a lock-lever pivoted to the setting-lever and its lower end engaging with the teeth of the segment. lVhen said setting-lever is moved out or in it rocks the crank-arm 19, and the roll 3 is moved to a greater or less angle to the axis of the drum B, therebyguidin g the apron across the face of the drum and making it travel around the drum in the desired lateral plane. In order to regulate the pressure of each of the rolls M N, we provide a turnbuckle 24 connecting the levers R B, so that the sliding boxes Q Q may be movedto and from each other, thereby giving a greater or less pressure to either of said rolls against its respective concave bed, as required, the pressure of said rolls to the concave beds being made by the hand-wheels X through the arms T S S and their connections.

By making the drum stationary and employing an apron which is drawn around it by suitable driving-rolls, the apron and drum perform the function of ironing or smoothing the goods as well as drying them, so that the use of the preliminary mangle is not at all times necessary.
